Abstract:
A device having high index layers is provided. The device includes an organic light emissive device, an air interface, a first planarization layer, and a first barrier layer. The first planarization layer is disposed between the air interface and the organic light emissive device and has an index of refraction of at least 1.6. The first barrier layer is disposed between the first planarization layer and the organic emissive device and has an index of refraction of at least 1.6.
